AHA and BHA are two terms used to group acids – e.g. Lactic and glycolic acids are AHAs – small, water soluble molecules that exfoliate multiple layers of skin. BHAs are oil soluble and generally a little less irritating for sensitive skin, e.g. salicylic acid. The fact that this contains a blend of both (glycolic, lactic, citric, salicylic, and tartaric acids feature) means that it’s a super powerful solution that really packs a punch.

We’ve noticed that many of you are loving our AHA 30% + BHA 2% Peeling Solution, and while we’re really happy that you’re enjoying it, we want to ensure that you’re playing safely. ⁣????⁣

The Ordinary’s AHA 30% + BHA 2% Peeling Solution is a 10-minute exfoliating facial for experienced users of Direct Acids. It offers efficient chemical exfoliation of the skin to target dullness and textural irregularities, with the aim of improving visible skin radiance with continued use. This formula also incorporates a Tasmanian pepperberry derivative to help reduce signs of irritation associated with acid use. ⁣⁣

Due to the high concentration of free acids, we would not recommend using this formula on sensitive, compromised or peeling skin. ⁣⁣

While exfoliating acids can result in quick visible benefits, we generally suggest indirect forms of skin exfoliation in favour of direct forms due to the potential inflammation and sensitivity associated with acid use. Please refer to NIOD’s Non-Acid Acid Precursor and the Ordinary Lactic Acid as an option for indirect exfoliation.
